When is the Evaluation of Extended CRPQ Tractable?
Summary: Characterizes structural conditions on ECRPQs (CRPQs extended with synchronous/regular/automatic relations) that govern evaluation complexity. Establishes a fine-grained trichotomy: classical evaluation can be PSPACE/NP/P and parameterized evaluation XNL/W[1]/FPT depending on query structure. (summarized by gpt-5-mini on Feb 09 2026)
